Resumption of Care (ROC)
Resumption of Care (ROC) is the OASIS time point completed when a patient returns to home health services after an inpatient facility stay of 24 hours or more for reasons other than diagnostic tests. The ROC assessment must be completed within 2 calendar days of the patient's return home or the agency's knowledge of the return, and it reestablishes the clinical baseline after the hospitalization.
When a ROC is required
A ROC follows a qualifying inpatient stay, meaning admission to a hospital, skilled nursing facility, or other inpatient setting for 24 hours or more for something beyond diagnostic testing, when the patient returns to the agency's care within the same home health episode. It pairs with the transfer OASIS the agency completed when the patient went inpatient. An emergency department visit without inpatient admission, or an observation stay that never converts to inpatient status under 24 hours, does not trigger a transfer or a ROC. The 2-day completion clock starts at the return home or when the agency learns of it.
Why the ROC assessment matters clinically
Patients rarely come home from the hospital the same as they left. The ROC re-baselines function, medications, wounds, cognition, and risk, and it feeds an updated plan of care for the remainder of the episode. It is also the natural point for medication reconciliation against the hospital discharge list and a drug regimen review, since transitions are where duplications, omissions, and dose changes concentrate. A rushed or superficial ROC is a common root cause of preventable rehospitalization in the first two weeks after discharge.
How hospitalizations touch PDGM payment
Under PDGM, a 30-day payment period is classified with an institutional admission source when it begins within 14 days of discharge from a qualifying inpatient stay, and institutional periods generally carry higher case-mix weights than community periods. A mid-episode hospitalization can therefore change the classification of the following payment period. The hospitalization itself also shows up in claims-based quality measures, so the ROC sits at the intersection of clinical recovery, payment classification, and measure performance.
Operational tips for clean ROCs
Missed ROCs are usually detection failures, not documentation failures:
- Track every patient transferred to an inpatient facility on a live census list
- Confirm actual discharge dates with the facility rather than relying on family report alone
- Schedule the ROC visit the day the patient returns whenever possible
- Reconcile medications against the facility discharge summary at the ROC visit
- Verify the transfer OASIS and ROC OASIS dates align before submission
Frequently asked questions
Does an emergency room visit require a ROC?
No. Only an inpatient stay of 24 hours or more for reasons other than diagnostic tests triggers a transfer and subsequent ROC. An ED visit or brief observation stay without qualifying inpatient admission does not, though the clinical team should still reassess the patient as needed.
Does a ROC start a new certification period?
No. The ROC resumes care within the existing 60-day certification period and its payment periods. The certification and recertification schedule continues to run from the original start of care.
Who completes the ROC assessment and by when?
A qualified OASIS clinician, meaning an RN, PT, OT, or SLP, completes it within 2 calendar days of the patient's return home or the agency learning of the return. It updates the comprehensive assessment and typically drives revised orders.
